Abstract
A method for compensating for alternator to battery voltage drop in charging systems lacking external remote sensing capabilities and utilizing serial communications. A controller utilizes an adaptive variable for determining an alternator output voltage setpoint that compensates for battery cable voltage losses, and adjusting the setpoint to achieve substantially constant battery voltage of the entire range of alternator loads.
